Specification of Letters Patent.

Application filed May- 20, 1909. Serial No. 497,296.

To all whom it may concern Be it knownthat we, JOHN H. ROADMAN, ofMonongahela city, Pennsylvania, and WILLIAM M. DRAvo, of Belle Vernon,Pennsylvania, both citizens of the United States, have invented acertain new and useful Take-Down Sling for Handling Glass Cylinders, ofwhich the following is a specification.

Our invention especially relates to the art of mechanically makingwindow glass, and its primary object is to provide convenient means forhandling the large glass cylin ders blown and drawn by machinery,especially to remove the same from vertical position after completion ofthe drawing process.

The invention is shown in several simple forms in the accompanyingdrawing, in which Figure 1 is a perspective view showing the preferredform of the device, and Figs.

2 and 3 show respectively modified forms.

Upon the completion of the process of drawing a glass cylinder, it hasbeen a difficult problem to remove the same from its suspended verticalposition over the glass and deposit it in horizontal position, uponholding devices, for cutting up the cylinder into sections. In suchapparatus as shown for example in the patent to Schmertz No. 890,306 ofJune 9th, 1908, there is employed a suspension cable upon which are apair of hooks adapted to engage the cylinder and swing its bottomoutward for lowering into horizontal position. There has been somedifficulty in placing and, adjusting these hooks in place, since theyare not free-to turn to horizontal position without slacking the cable,and for other reasons. In our invention, the cable 4 carries a trolley5, by which the sling or holder is suspended. In

Fig. 1, this device is shown as comprising a rigid handle 8 engaged bysliding rings 7 on the chain 6 and the handle provided with a stop 9 asshown. The handle has attached to one of its rigid forks 10 ailexiblemetal strap lllprovided with wooden guard blocks 12, and its free endhas a separable fastening in the form of a slot 13 to engage a pin 14 onthe other fork of the handle. By this construction the sling may beturned-in its substantially as described.

support and may be brought to horizontal position, slipped around thecylinder and adjusted to place and locked, after which the mere upwardpull of the supporting chain 6 will lift the handle to vertical positionout of the way. This enables the work-- men to attach the sling or strapto the cylinder with ease and from either side, without drawing downmore slack of the cable.

In the modification of Fig. 2, the strap 11 is suspended by handle 16which is pivoted at 17 to a suspending rod 15 on the block 5, and thestrap 11 has simple hooked ends 18 for closing. In the modification of'Fig. 3 the handle 19 of the strap is rigid and prior devices, of a moresecure hold on the cylinder, a more easy adjustability, cheapness, andthe capability of bringing the handle to horizontal position and thenautomatically lifting the handle out of the way as the pulling strain isapplied. It will be noted that the flexible strap is rigid in a lateraldirection so that it can readily be moved by the handle and this handlemay be of any desired length so as to avoid the necessity of getting toonear the hot glass.

What we claim as new and desire to secure by Letters Patent is:

1. Apparatus for taking down glass cylinders, comprising a strap adaptedto be passed around a glass cylinder to be taken down and having meansfor effecting a separable connection of its ends, a handlefixed to saidstrap and projecting radially therefrom, and a suspending device .forthe handle, said handle and strap being substantially rigid when movedin the direction of the axis of the cylinder to be taken handleintermediate of its ends, whereby the handle and strap may be turnedfrom-a-vertical to a horizontal position, the handle and strap beingsubstantially rigid when moved in the direction of the 'axis of thecylinder,

3. In apparatus for taking down glass cylinders, a strap adapted tosurround the cylinder to be taken down, a handle connected to said strapand extending radially therefrom, and a supporting device having a.slidable engagement with the handle, the handle having means forlimiting the sliding movement, and said handle and strap being rigidlyconnected with respect to movement in the direction of the axis of thecylinder to be taken'down, substantially as described.

4. Apparatus for taking down glass cylinders, comprising a flexiblemetal strap adapted to surround the cylinder to be taken down and havinga non-metallic inner portion for contact with the cylinder, a handlefixed to said strap and extending vertically therefrom, and supportingmeans connected to the handle, the handle and strap being substantiallyrigid when moved in the direction of the axis of the cylinder, substantially as described.

5. A device for taking down glass cylinders, comprising a sling havingseparable ends and adapted to surround the glass cylinder, ahandle fixedto the cylinder near one of its ends, and a suspending device having inoasoa swing connection with the handle, said handle and sling beingconstructed and connected to be substantially rigid when moved in thedirection of the axis of the cylinder, substantially as described.

6. A. device for moving freshly drawn glass cylinders from a vertical toa horizontal position, comprising a sling member having separable endsand adapted to surround the said cylinder, a rigid handle fixed to saidmember to maintain a rigid relation thereto when moved in the directionof the axis of the cylinder, and a suspending device having a swingconnection with the handle, substantially as described.

In testimony whereof we have hereunto signed our names in the presenceof the two subscribed witnesses.
